INTELLIGENT ULTRASONIC DETECTION OF WALKING STICKS FOR THE BLIND

Visually impaired individuals face significant challenges in navigating their surroundings independently and safely. This project presents the design and implementation of an intelligent walking stick equipped with ultrasonic sensors, a voice assistance module, and a water detection unit. The system is developed to provide real-time alerts to the user using vibrations and voice feedback when obstacles or wet surfaces are detected. Additionally, it incorporates a medicine reminder feature and an emergency alert mechanism through voice prompts, enhancing both daily usability and critical safety for the user. By integrating low-cost components like the Arduino UNO, APR33A3 voice module, and ESP8266 for wireless connectivity, the proposed system offers a reliable and affordable solution for aiding the visually impaired.
